Risstenni was a female Wookiee who lived on the planet Cularin during the time of the Clone Wars. Circa 21 BBY, Risstenni's son, Chywarra, was abducted by the Wyrd, a group of Tarasin Force witches. They took him to the extinct volcano Cloud Mountain, where they placed him inside the Hand artifact, a Force-imbued statue that allowed its controller to draw power from the artifact's occupant. Risstenni traveled to Cloud Mountain in search of her son and was captured by the Wyrd, who offered to let her take Chywarra's place inside the artifact. She accepted, entered the statue, and was killed during a Wyrd ritual. She was transformed into a dark side spirit and, in her new form, encountered a group of agents that had come to Cloud Mountain to search for her and Chywarra.
